Adjusting mid-cycle is perfectly OK if you are making the right adjustments. I agree with Dylan and Steve here in that it is probably the Dbol that is causing your sleeping issues. However, I can't simply tell you to cut it out. Dbol should be tapered if you ask me for one and secondly, maybe you should just cut it back to 25mg or 20mg and see how you feel.
My first cycle was Dbol alone, second was dbol and test, third was dbol, test and deca. I turned into a beast!
